About The Position

St. Jude Children’s Research Hospital is seeking an experienced scientific leader to serve as Lead Scientist - Directing of the Cryo-Electron Microscopy and Tomography (Cryo-EM/Cryo-ET) Center. This position will play a key role in overseeing daily operations of the Center, advancing cryo-EM and cryo-ET workflows, supporting institutional research programs, and leading a team of scientists responsible for user training, instrument operations, and technology development. The Cryo-EM/Cryo-ET Center operates in close partnership with the Center of Excellence for Structural Cell Biology (CoE-SCB), which focuses on advanced method development and next-generation workflows in tissue cryo-ET, cryo-volume EM, and correlative imaging. Together, these programs provide investigators with access to state-of-the-art instrumentation, computational infrastructure, and scientific expertise supporting both routine structural biology and advanced methodological innovation. The successful candidate will contribute to the strategic growth of cryo-EM / cryo-ET capabilities at St. Jude and will work closely with faculty, staff scientists, computational teams, including from the Center of Excellence for Structural Cell Biology (CoE-SCB). The position combines scientific leadership, operational oversight, user support, and team management within a highly collaborative and rapidly expanding environment. The Cryo-EM/Cryo-ET Center supports a broad range of structural biology and cellular imaging projects spanning pediatric cancer, infectious disease, neuroscience, immunology, and fundamental biology. The Center houses multiple state-of-the-art cryo-EM systems including Krios G3i, Krios G4, Krios 5, Talos Arctica, Aquilos 2 cryo-FIB, and advanced computational infrastructure for high-throughput cryo-EM and cryo-ET workflows.
